Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, RUSSELL D. BARTLETT, of Ban or, in the county ofKennebec and State o' Maine, have invented an Improved Machine forCutting Veneering or other Thin Strips of food JromLogs or` Oylin ders;and I do hereby declarethat the same is fully described and representedin the following speciflcation and the accompanying drawings, of which-Figure `l, is a t-op view. Fig. 2, afront elevation. Fig. 3, a vertical,central and In the said drawings, A, denotes the bed rails or supportingframe of the operative mechanism to be described, such part, A, beingconstructed like the bed rails of an ordinary turning lathe. The saidpart, A, supports a head stock, B, anda tail stock, which respectivelycarry two arbors, D, E, arranged with respect to one another as shown inthe drawings. One of these `(vin, 1),) the main driving arbor-while theother (E,) is the centering arbor. The said main arbor carries on itsouter end, a dog or chuck F, and a centering point or center, The otheror centering arbor has a rack,

ion, ZJ, engages with the said rack and is put in operation by gears, c,d, and acrank, e, the whole being arranged as shown in thedrawingsandfor the purpose of imparting to` the arbor, E, an endwisemotion either inner end of the centering arbor is furnished with acylindrical socket, f, for the reception of a journal g, extending froma rotary center, I, formed as shown in Figs. 1, 2, 3, and moreparticularly as exhibited in longitudinal section in Fig. 1l. Thiscenter fixes itself to a piece of wood when the latter is placed betweenthe center and the chuck, F, of the driving arbor. The object of thesaid rotary center is to prevent displacement `of the axis of the blockduring the operation of reducing the block by the main plane or cutter,K. The said cutter, K, is arranged in and supported by a carriage, L, soapplied to the head and tail stocks as to be capable of being movedvertically between them by means of two racks, h, h, which engage withtwo pinions, 11, z', aiiixed on a horizontal shaft 7s, arranged as shownin the drawings. The said shaft, 7c, receives rotary motion from adriving shaft, M, by means of two pulleys,

Z, m, and two gears, n, o, arranged as shown 26,556, dated December27,', ,1859.`

in the drawings, the saidpulleys being sup-` plied with an endless band,@for transmit-i l ting motion from one to the other.` The` said drivingshaftoperates the mainarborco by means of two gears, RYQ,` applied tothem y respectively. i l i f Directly in frontof the main cutter,"K, yand somewhat above the f same is a throat@ gage, N, which` is supportedinipositionby l means of pivots, s, s, projecting intolitsztwofg i uppercorners, and sustained` in y adjustable y boxes, O, O, fastened tothecutter: carrierby` l screws, t, t, extended` through slots formed in. ilthe said bearings, O, O.` Said pivotsare aplplied to the bores in suchmannersolas to w f1 be capable of being "drawn out` of or end# wise inthe same, so `as to admitlofthe rejo moval of the throat gage, the`pvotsbeingff held in place by set screws, u, u," extendingju' throughthem respectiyely `and screwed against the cutter carriage. Furthermore,the throat gage supports two edge cutters 11 P', P, applied to it bymeans of clamps fv, (o, l `5 extending through slots,`/L`U,/io,inadeinthew; o'age. y "y f M c By the above modeof applying the throat, gageto the cutter carriage, we not only have the means of turning itoutofthewayofll` the cutter, K, preparatoryto itsreduction of 85", the log to aproper state for the formation ofz" veneeringtherefrom but lwe can atany time l` y u that it may be desirable to sharpen either 211 the mainor the edge cutters,;move thefthroat` f l l gage upward so asto enableusto` gain "alcapQO cess to good `advanta,g fe to the cutting edge ofieither ofthe said cutters;` f i 1 In the operation of the machine, themain 1 cutter carriage, while the main arbor "and 1002` 1 are inrevolution, `will be` regularlyumoved 95,` downward so as to cause `theveneering tofbe f taken in a spiral fornifronrthe block or` loo'.
